Abstract
Provided is a device for titanium continuous casting () capable, even when continuously casting large diameter titanium ingots or titanium alloy ingots, of suppressing component segregation thereof. The device for titanium continuous casting () comprises: a mold () having an upper section having a circular upper opening () for pouring in molten metal (), and a bottom section having a lower opening for continuously drawing ingots (); and a plurality of plasma torches () to heat the molten metal in the mold () from the upper opening () side. The plurality of plasma torches () are disposed so that the amount of heat input to the molten metal () present in the outer circumference enclosing the center of the upper opening () is greater than the amount of heat input to the molten metal () present in the center of the upper opening ().
